This paper introduces four kinds of orthorectification algorithms, such as polynomial correction method, collinear equation correction method, neural network correction method and rational function model correction method. On the basis of introducing the principle of the above methods, the advantages and disadvantages of different orthorectification methods are summarized. Finally, the multispectral and full-color image data of the GF-1 satellite are processed by using the rational function model correction method. The results show that orthorectification can eliminate the distortion caused by various factors in the process of remote sensing image, and can make full use of the data resources obtained by satellite to provide information service for land resources management.

Intelligent vehicle monitoring system is collecting and processing the large amounts of information all the time. The paper applies data warehouse technique to intelligent vehicle monitoring system to store and manage the information. Based on the analysis of the subject field in the system and the design of dimension table, the system logical model and physical data model, the data warehouse of system is built. And, the data in the data warehouse are analyzed and summarized by the data analysis and display tools. Decision-makers can clearly and intuitively see the result, and this can offer the decision foundation for development of China's transportation.

Based on radar system function module 04-combination as the research object, this paper expatiates the establish process of the cross-neural network module of this module electromagnetic pulse action particularly, and designs evaluate system of this kind of electron system electromagnetic pulse effect, using the detailed process that BP-RBF cross neural network evaluation algorithm predicts this module. Finally, according to the evaluate experiment of 08- combination testing the effect of this evaluate system, results indicate that it is feasible that using this evaluate system evaluates electromagnetic pulse effect of electronic system.

On the basis of the vehicle license plate location, an image grey vertical projection segmentation approach based on the distribution character segmentation is proposed in this paper. A two-stage approach consisting of coarse and accurate segmentation is adopted. It can increase the accuracy of the segmentation and has good segmentation speed. And in recognition process, character features are extracted from character segmentation results, in order to identify character exactly, an improved template matching method is used to character recognition. Experimental results show that character segmentation method is efficient and quick and recognition algorithm is applicable.

This paper briefly introduces the recognition process on palm shape and mainly introduces feature parameter extraction process on palm shape. By statistic experiment eight feature parameters are extracted from many parameters of palm shape. They are the length of pinkie, the length of ring finger, the length of middle finger, the length of forefinger, the length of thumb, the width of ring finger, the width of middle finger, the width of palm. Experiment indicates that using these eight feature parameters to identify palm can reach high veracity and rapidity.

In order to monitor network transmission effectively and safely and detect suspicious behavior in the network, the intrusion detection software was solidified in embedded hardware development board based on the SBC84620. The system adopted real-time Linux operating system used in the field of industrial widely, achieved real-time detection and prevention to hacking attack including port scans, buffer overflow attacks, backdoor attack, DOS attacks, and other information-gathering network, and so on, reduced development costs, increased data processing speed.
